Aegypiinae
Aegypiinae is one of two subfamilies of Accipitridae that are referred to as Old World vultures, the other being the Gypaetinae. They are not closely related to the Gypaetinae, and are instead a sister group to the serpent-eagles (Circaetinae). Presently found throughout much of Africa, Asia, and parts of Europe, fossil evidence indicates that as recently as the Late Pleistocene, they ranged into Australia. Taxonomy The subfamily Aegypiinae was introduced (as the family Aegypiidae) in 1924 by the British zoologist William Lutley Sclater with ''Aegypius'' Savigny, 1809, as the type genus. The cladogram of the Aegypiinae shown below is based on a molecular phylogenetic Molecular phylogenetics () is the branch of phylogeny that analyzes genetic, hereditary molecular differences, predominantly in DNA sequences, to gain information on an organism's evolutionary relationships.

Old World Vultures
Old World vultures are vultures that are found in the Old World, i.e. the continents of Europe, Asia and Africa, and which belong to the family Accipitridae, which also includes eagles, buzzards, kites, and hawks. Old World vultures are not closely related to the superficially similar New World vultures and condors, and do not share that group's good sense of smell. The similarities between the two groups of vultures are due to convergent evolution, rather than a close relationship. They were widespread in both the Old World and North America during the Neogene. Old World vultures are probably a polyphyletic group within Accipitridae, belonging to two separate not closely related groups within the family. Most authorities refer to two major clades: Gypaetinae ('' Gypaetus, Gypohierax'' and '' Neophron'') and Aegypiinae (''Aegypius'', ''Gyps'', '' Sarcogyps'', '' Torgos'', '' Trigonoceps'' and possibly '' Necrosyrtes''). The former seem to be nested with Perninae hawks, while th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accipitridae
The Accipitridae () is one of the four families within the order Accipitriformes, and is a family of small to large birds of prey with strongly hooked bills and variable morphology based on diet. They feed on a range of prey items from insects to medium-sized mammals, with a number feeding on carrion and a few feeding on fruit. The Accipitridae have a cosmopolitan distribution, being found on all the world's continents (except Antarctica) and a number of oceanic island groups. Some species are migratory. The family contains 256 species which are divided into 12 subfamilies and 75 genera. Many well-known birds such as hawks, eagles, kites, harriers and Old World vultures are included in this group. The osprey is usually placed in a separate family ( Pandionidae), as is the secretary bird ( Sagittariidae), and the New World vultures are also usually now regarded as a separate family or order. Karyotype data indicate the accipitrids analysed are indeed a distinct monophyletic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gypaetinae
The Gypaetinae is one of two subfamilies of Old World vultures the other being the Aegypiinae. Some taxonomic authorities place the Gypaetinae within the Perninae hawks. They are presently found throughout much of Africa, Asia, and southern Europe, hence being considered "Old World" vultures, but as recently as the Late Pleistocene, they were also present in North America. A 2005 study found ''Madagascar serpent eagle, Eutriorchis astur'' to be closely related.

Hooded Vulture
The hooded vulture (''Necrosyrtes monachus'') is an Old World vulture in the order Accipitriformes, which also includes eagles, kites, buzzards and hawks. It is the only member of the genus ''Necrosyrtes,'' which is sister to the larger '' Gyps'' genus, both of which are a part of the Aegypiinae subfamily of Old World vultures. It is native to sub-Saharan Africa, where it has a widespread distribution with populations in southern, East and West Africa. It is a scruffy-looking, small vulture with dark brown plumage, a long thin bill, bare crown, face and fore-neck, and a downy nape and hind-neck. Its face is usually a light red colour. It typically scavenges on carcasses of wildlife and domestic animals. Although it remains a common species with a stable population in the lower region of Casamance, some areas of The Gambia, and Guinea-Bissau, other regions such as Dakar, Senegal, show more than 85% losses in population over the last 50 years. Threats include poisoning, hunting, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Vulture In Tanzania 3118 Cropped Nevit
A vulture is a bird of prey that scavenges on carrion. There are 23 extant species of vulture (including condors). Old World vultures include 16 living species native to Europe, Africa, and Asia; New World vultures are restricted to North and South America and consist of seven identified species, all belonging to the Cathartidae family. A particular characteristic of many vultures is a bald, unfeathered head. This bare skin is thought to keep the head clean when feeding, and also plays an important role in thermoregulation. Vultures have been observed to hunch their bodies and tuck in their heads in the cold, and open their wings and stretch their necks in the heat. They also urinate on themselves as a means of cooling their bodies. A group of vultures in flight is called a "kettle", while the term "committee" refers to a group of vultures resting on the ground or in trees. A group of vultures that are feeding is termed a "wake". Taxonomy Although New World vultures and Ol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lappet-faced Vulture
The lappet-faced vulture or Nubian vulture (''Torgos tracheliotos'') is an Old World vulture belonging to the bird order Accipitriformes, which also includes eagles, kites, buzzards and hawks. It is the only member of the genus ''Torgos''. It is not closely related to the superficially similar New World vultures, and does not share the good sense of smell of some members of that family of birds. The lappet-faced vulture was formerly considered monotypical, but now is separated into two subspecies. The nominate race lives throughout Africa. The subspecies '' T. t. negevensis'', differing considerably in appearance from African vultures (as described below) is endemic to the Arabian Peninsula. Name The scientific name is Greek, meaning "Cartilage-eared Vulture". Distribution This species is patchily distributed through much of Africa and the Arabian Peninsula, though it is absent from much of the central and western parts of the continent and declining elsewhere in its range. ...

Aegypius
''Aegypius'' is a genus of Old World vultures found in the subfamily Aegypiinae. Of the three species in the genus, only the cinereous vulture is extant. The cinereous vulture (''Aegypius monachus'') is a creature that is hard to find as it is “a near threatened raptor that occurs in isolated populations across its range” (Çakmak). There were studies being conducted on the cinereous vulture and it indicates “that the Turkish birds hold, along with those from the Caucasus, an intermediate position between European (Balkan and Iberian) and North Asian (Mongolian) lineages” (Çakmak). The genus name ''Aegypius'' is a Greek word (αἰγυπιός) for 'vulture', or a bird not unlike one; Aelian describes the ''aegypius'' as "halfway between a vulture (''gyps'') and an eagle". Some authorities think this a good description of a lammergeier; others do not. Aegypius is the eponym An eponym is a noun after which or for which someone or something is, or is believed to be ...

Cinereous Vulture
The cinereous vulture (''Aegypius monachus''), also known as the black vulture, Eurasian black vulture, and monk vulture, is a very large Raptor (bird), raptor in the family Accipitridae distributed through much of temperate Eurasia. With a body length of , across the wings and a maximum weight of , it is the largest Old World vulture and largest member of the family Accipitridae. ''Aegypius monachus'' is one of the largest birds of prey and it plays a huge role in its various ecosystems by eating carcasses, which in turn reduces the spread of diseases. The vultures are constantly exposed to many pathogens because of their eating carrion. A study of the gastric and immune defense systems conducted in 2015 sequenced the bird's entire genome. The study compared cinereous vultures to bald eagles, finding positively selected genetic variations associated with respiration and the ability of the vulture's immune defense responses and gastric acid secretion to digest carcasses.
